Consistent individual differences (CIDs) in behavior are a widespread phenomenon in animals, but the proximate reasons for them are unresolved. We discuss evidence for the hypothesis that CIDs in energy metabolism, as reflected by resting metabolic rate (RMR), promote CIDs in behavior patterns that either provide net energy (e.g. foraging activity), and/or consume energy (e.g. courtship activity). In doing so, we provide a framework for linking together RMR, behavior, and life-history productivity. Empirical studies suggest that RMR is (a) related to the capacity to generate energy, (b) repeatable, and (c) correlated with behavioral output (e.g. aggressiveness) and productivity (e.g. growth). We conclude by discussing future research directions to clarify linkages between behavior and energy metabolism in this emerging research area.
行为的一致个体差异（CIDs）在动物中是一种普遍现象，但导致这些差异的原因尚不清楚。我们讨论了这样一种假设的证据，即能量代谢中的 CIDs，如静息代谢率（RMR），促进了行为模式中的 CIDs，这些行为模式要么提供净能量（例如觅食活动），要么消耗能量（例如求偶活动）。通过这样做，我们为将 RMR、行为和生活史生产力联系起来提供了一个框架。实证研究表明，RMR 与（a）产生能量的能力、（b）可重复性和（c）与行为输出（例如攻击性）和生产力（例如生长）相关。最后，我们讨论了未来的研究方向，以澄清这一新兴研究领域中行为和能量代谢之间的联系。
